Abstract


Over the past decades, switched to Web services. Web services offers flexibility and interoperability of independent functions that are platform independent software applications and perform a specific task. Private and public institutions in the developed nations are offering web services. These include service such as online appointment booking for patients, air, train, hotel bookings and online banking. Semantic Web services are a synergetic confluence of semantic Web and Web services. They have the potential to offer value-added services by automatically discovering and assembling Web services to accomplish a domain task. Automated Web service composition is a key research area concerning Web services as it reduces human effort. In this regard, the challenge is service discovery and communication between independent services. In this paper, the framework of semantically automated/enhanced composite Web services is proposed. A scenario of planning a trip is taken into consideration and as a proof of concept. A trip planner application (TPA) is developed, based on the proposed framework. TPA is a trip planner capable of automatically identifying the best deals for the users. Based on certain limited input parameters, the trip planner service would automatically identify other related services and invoke them. For accomplishing the task of planning a trip, for instance flight-booking service would invoke hotel reservation service by using flight details, with least possible human effort and interaction with the service. This service would automate the process of invoking other related services.
